Formula of the Institute
Prima Societatis Iesu Instituti Summa (Formula Instituti)

Five chapters defining the new order's identity: serving 'under the banner of the cross' and under the Roman pontiff, the fourth vow of obedience to the pope regarding missions, poverty, the absence of choir and of a distinctive habit, and the primacy of ministries of the word, the Exercises and works of charity. It is the founding charter of the Society.
